Save rate
Also known as: Bookmark rate
The percentage of impressions that resulted in a bookmark — a strong indicator of reference-worthy content.
In depth
Save rate (also called bookmark rate) is the cleanest signal that a post is genuinely useful. Unlike likes, which are often reflexive, bookmarks require deliberate intent — the reader thinks 'I want to come back to this.'
The algorithm weights bookmarks heavily because they're a forward-looking signal: posts with high save rates predict future re-engagement. Lists, frameworks, and reference-style posts typically achieve the highest save rates.
